In addition, the cut (2) of the clamp part (4) is the electric wire '1lr (
It is formed with an opening that is smaller than the outer circumference of P), and the synthetic resin clamp member (1) has elasticity, so the conduit (P) is pressed against the opening width of the cut (2). It is held in the clamp part (4) by pushing it into the recess (3) so that it is expanded.In this case, the recess (3) is held by the flattening of the expanded cut (2). The inner circumference'! (20) is crimped to the electric wire 'F? (P), and the conduit tube (
P) can be reliably maintained. In this example,
It is formed in a direction perpendicular to the piping direction of the conduit (P) held in the clamp part (4) and the dividing plane of the dividing members (Ia) (lb), and therefore, in the dividing direction of the dividing member (1a01b). Regardless, the conduit (P) can be reliably held in the clamp part (4).
